The Menlo Park City Council will consider Tuesday a proposal by Facebook to expand its headquarters, which includes a pledge to allocate millions of dollars generated by the project to tackling the area’s traffic and affordable housing issues.

Facebook plans to add 126,000 square feet of commercial space to its complex, which already stretches from the Belle Haven neighborhood to the bay. The expansion will occupy a 59-acre tract adjacent to its Frank Gehry-designed Building 20. In addition to offices, the social networking company also plans to build a hotel, which it promised will yield at least $1.25 million per year for the city in taxes.

A report by a city planner said the project’s buildings would have a minimum value for tax purposes of $695 million and would generate revenue for Menlo Park of approximately $2.1 million a year for 10 years after they are occupied, and $1.8 million a year thereafter. The company also plans to spend more than $7.8 million on affordable housing and more than $3 million to address traffic congestion.

John Tenanes, Facebook’s vice president of global facilities and real estate, said the proposal reflects efforts to be a good corporate citizen. He said the company has met with Menlo Park officials several times since it moved its headquarters from Palo Alto six years ago.

“Any time you have a major employer like a Facebook who is desiring to grow in your community, there is always going to be impact,” City Manager Alex McIntyre said. “There will be additional burdens, but there will also be additional benefits, and the question is will those burdens balance with the benefits.”

Facebook committed to a program in Belle Haven that would subsidize rents for 22 units for five years in an effort to make housing more affordable to teachers, firefighters and other service workers. It also plans to build at least 1,500 housing units on property it bought from Prologis in 2015. The company says 15 percent of those units will be offered at below-market rates.

Not everyone is convinced that Facebook’s millions will be enough to mitigate the impact its growing presence has had.

“Giving money doesn’t really solve the problem or address the issues of social justice,” said Cynthia Cruz, program director at Envision Transform Build East Palo Alto, a coalition dedicated to helping displaced residents in that city, which is close to Facebook headquarters. “I’m not sure that giving money is a solution, versus sitting with the community and listening.”

Finding housing for low-income residents of color is the largest problem the region faces right now, according to Cruz. Just this year, she said, three of the coalition’s youth members had to move to Sacramento and Antioch with their families, who could not afford the area’s increasing rents.

Traffic, too, is a worry. A third of Facebook’s employees live in San Francisco. Many ride company shuttles, but the number of solo drivers has increased this year after San Francisco reduced the number of shuttle stops.

Facebook wants to take another look at transportation options, including possibly restoring the long-closed Dumbarton rail line across the Bay. The defunct connection passes the headquarters, including the planned expansion. The company said it would pay $1 million for a feasibility study and an additional $1 million toward implementing recommended changes.

“It’s exciting to see them look for solutions for a corridor that’s heavily impacting them,” said Susan Shaheen, co-director of UC Berkeley’s Transportation Sustainability Research Center. “It’s an acknowledgment by the private sector that they want to contribute to this and they want to contribute to public use of these corridors.”

The council is expected to review the proposal at Tuesday’s meeting and offer comment as part of its negotiations with Facebook. A vote will likely come in the fall.
